Description

PDF

HERRINGBONE PLANETARY GEAR is used as a radial bearing, but later I will also send the Axial bearing option.
Axial bearing will be much better for this purpose but also more complicated to compose.
I will provide more precise information and a bearing model when I am done with the design.
I will add other options or correct any shortcomings soon.

12. 05. 2022 added update 1 with thrust bearing:
The thrust bearing parts are numbered from 11 to 16. A 6 mm diameter ball is required as a rolling segment. Airsoft ammunition (6 mm plastic ball) may be used.
shaft + gear_bearing parts can be used as a replacement.

Thrust bearing can be remixed.
